6) f(x) = x - 4 Evaluate lim f(x). x 2 7) Joey the mountain climber is hiking up a mountain with slope 2/3. Using his altimeter he finds that he is gaining altitude at a rate of 6000 feet/hour. How fast is he hiking? 8) 9) Evaluate the limit lim x-2 X - 52 6 - x - 4 Determine, if it exists, lim x-5+ 6 X x2 4 X X 6) f(x) = x - 4 Evaluate lim f(x). x 2 7) Joey the mountain climber is hiking up a mountain with slope 2/3.
